[SMM Analysis] Italy plans to hold its first MACSE (Mechanism for the Procurement of Electricity Storage Capacity) energy storage capacity auction in the first half of 2025. This mechanism, implemented by Terna, the Italian Transmission System Operator (TSO), aims to support energy storage projects by offering indexed contracts for up to 15 years, covering up to 100% of asset capacity. MACSE is viewed as a game-changing policy support mechanism that offers crucial downside risk protection for infrastructure investors and ensures high bankability for projects due to the strong credit counterparty—the government-backed system operator, Terna.
